MikeE,
I stopped at my local goodyear place...not the chain type, but the local garage where they still have mechanics and understand what you are looking for. My guy figured out what size tire was what and could do the math that compared stock tires to radials.
They might be able to help you by ordering in the tire you need.
Maybe you already tried that...if so...never mind.
I know my local Sams and Fleet Farm would not mount a tire for me unless the book said it "belonged" on my truck...go figure..their books did not even list my truck.
I was surprised that the local guy beat Sams anyway when it came to price. Best of all, the customer service was personal as compared to the big box places.
